How many users have updated to iOS 9 after 24 hours of availability?

According
to the first report from Mixpanel, over 12% of iPhone owners
have updated to the latest version of the mobile operating system within
24 hours of availability, which is a slightly slower pace than what we
saw after the launch of iOS 8 last year, which managed to penetrate 16% of the market in a single day.

“iOS
9 has received 12% adoption in the last 24 hours and is being adopted
similar to iOS 8 last year,” says Mixpanel. “However, one issue for it
being substantially slow compared to iOS 7 is that servers are having
trouble keeping up right now as people update.”

As 9to5Mac
notes, over 20% of users had moved onward and upward to iOS 7 within
the first 24 hours. When iOS 8 rolled around a year later, the ridiculous storage requirements caused many iPhone users to hesitate, as they’d be forced to delete photos or apps in order to make room for the update.

Apple
fixed that issue this year by limiting the download to a single
gigabyte, but it appears another issue arose, as some users haven’t been
able to update on account of server overload. Personally, I was able to
update both an iPhone 6 and an iPad Air 2 immediately after requesting
them from the Settings menu, but others haven’t been as fortunate.

All
in all, the 24 hour adoption benchmark isn’t an especially important
one, but it is interesting that Apple can’t reach the heights of iOS 7
with any subsequent updates. We’ll keep an eye on the adoption rate in
the coming days to see if anything changes
